Dry Strength Resin

Balaji chem solutions dry strength resin comes in premium quality which adds dry strength to the paper. They are mainly available in three forms that is aniomic, cationic, and amphoteric. However, the main aim of dry strength resin is to surge the strength per unit between fibres in any paper. Indeed, it also helps in achieving strength goals while maintaining higher dewatering rates and lower density of paper

Application:

  • Dry Strength Resin can be used in all kinds of writing & printing, duplex board, Kraft paper.
  • It may be used after addition of resin and best addition point is mixing chest. Before the addition of Dry Strength Resin, it should be diluted to 20% solution.
  • Duplex board addition point is the protective and bottom layer.
  • The recommended dosage of Dry Strength Resin is 0.4% to 0.6% on the dry paper basis to get the desired result.
  • It can reduce the alum requirement
  • Help to boost the tensile strongness of paper
  • Help in saving energy
  • Surge the stiffness of weaker sheet of paper

Helps in reducing fibre costs by replacing long fibre with short fibre

Frequently Asked Questions

 

1. What is the purpose of dry strength resin?

Dry strength resin is used to improve fiber-to-fiber bonding in paper. It increases tensile strength, burst strength, stiffness, and internal bond, helping paper meet strength specifications without increasing GSM.

2. How is it applied in manufacturing?

Dry strength resin is added at the wet end of the paper machine, usually in the mixing chest or machine chest. Proper dosage and good mixing are important for effective bonding and retention.

3. What are the different types of DSR?

The main types are cationic, anionic, amphoteric, and natural polymer-based dry strength resins. Each type is selected based on furnish quality, system charge, and paper grade.

4. What are the commercial benefits?

Dry strength resin helps reduce raw material costs, minimize rejections, improve machine runnability, and maintain consistent paper quality, leading to better production efficiency.

5. How does it differ from wet strength resin?

Dry strength resin improves paper strength in dry conditions, while wet strength resin maintains strength when paper is exposed to water or moisture.

6. Why is my paper becoming brittle despite using DSR?

Over-dosage, poor distribution, or incorrect resin selection can cause brittleness. Charge imbalance and lack of flexibility in the fiber network may also contribute.

7. Can DSR improve machine speed?

Yes. By improving sheet strength and reducing breaks, dry strength resin can support higher machine speeds and smoother operation.

8. How does it improve recyclability?

Dry strength resin enhances fiber bonding without permanently locking fibers, allowing paper to be repulped more easily compared to wet strength resins.

9. Is tapioca starch an industrial starch?

Yes. Tapioca starch is widely used as an industrial starch in paper manufacturing after chemical modification for better performance.

10. What is cationic starch for paper?

Cationic starch is a modified starch with a positive charge. It improves dry strength by bonding effectively with negatively charged cellulose fibers in paper.
